  • Systems and methods for managing purge pathway pressure in turbocharged engines
    Patent number: 10302031
    Abstract: Methods and systems are provided for operating an evaporative emissions system in a turbocharged engine. In one example, a method may include pulsing open a canister purge valve responsive to the turbocharged engine entering a boosted mode of operation. The canister purge valve may be opened for a duration long enough to close a check valve coupled between the canister purge valve and an intake of the engine.
    Type: Grant

  • Assembly and method for receiving hydrocarbon material
    Patent number: 6553976
    Abstract: An assembly 10 which includes primary and secondary hydrocarbon material reception and storage devices 22, 24 in a cascaded and communicative relationship. Particularly, the device 24 receives and stores hydrocarbon emissions 20 which emanate from the device 22. Device 24 further includes a filter 50 through which purging air is communicated to the devices 22, 24. Further, device 24 includes a condensation removal portion 52 which allows condensation 92 to be vented from the device 24 and a selectively closeable vent portion 54 which allows the device 24 and the assembly 10 to be periodically tested.
